OBJECTIVE Water-pipe smoking has become a serious public health threat worldwide. In order to raise awareness of adverse effects and transmission of bacteria via water-pipe smoking, we aimed to identify the bacteria and their antimicrobial resistance profiles that colonize different parts of waterpipes. METHODS We examined totally 182 water pipes from 7 lounges (in Turkey) used in public places and we collected 728 culture samples in total by microbiological methods. We used disposable sterile swabs to sample the inside and outside of the mouthpiece, and the handling piece and sterile injectors were used to collect 5 mL of water from the water pipe bowl. RESULTS There was a significant (p less then 0.05) difference in microbial contamination (growth/presence of bacteria and fungi) among the parts of the water pipes sampled. There was a significant (p less then 0.05) difference in the number of bacteria growing (microbial load) among the parts of the water pipes. Only one narghile lounge out of seven, which had 13 water pipes, had a hygiene procedure. The water jars are often contaminated with Gram-negative bacteria. CONCLUSION Water pipes, especially the interior and outer part of the mouthpieces and the handle, are colonized by microbes and pose a risk of infection. Procedures for water pipe hygiene should be developed, periods should be defined, and the owners and employees of establishments and water-pipe smokers should be educated in this regard. Water-pipe smoking is a threat to public health and should be regulated by the state.OBJECTIVE Hepatitis E infection is one of the most frequent acute hepatitis in the world. Currently five human genotypes with different geographical distributions and distinct epidemiologic patterns are identified. In Slovakia, only rare cases of hepatitis E have been reported in recent years. Therefore, the aim of the study was to evaluate the prevalence of anti-HEV total antibodies and the main risk factors for HEV in the general population in Eastern Slovakia. METHODS Detection of anti-HEV total antibodies samples was done by a commercial enzyme-linked immunosorbent assay (ELISA) kit. RESULTS Of 175 hospitalized patients included in the study, 76 (43.5%) showed positivity for anti-HEV total antibodies. No statistically significant differences were found in anti-HEV positivity between men and women or in the groups of different living areas (town/village - urban/rural). CONCLUSION Prevalence of anti-HEV total antibodies of hospitalised patients was high. The risk factor significantly associated with antibody positivity was eating raw meat. Other factors, such as sex, age, living area and contact with animals were not associated with antibody positivity.OBJECTIVE The study aimed at assessing the potential benefit of prostate health index (PHI) for early detection of prostate cancer (PCa) and the use of PHI as a marker predicting the presence of PCa before performing prostate biopsy. METHODS The study comprised 55 males who underwent prostate biopsy. Before the procedure, blood samples were collected to test prostate specific antigen (PSA) and free/total PSA ratio (%fPSA) and PHI was calculated. Receiver operating characteristic (ROC) analysis was used to assess the benefit of these values for predicting the presence of PCa. RESULTS Based on histological examination 31 males were diagnosed with PCa, the remaining 24 were negative. Among the PCa patients, 39% had a Gleason score of 6, 26% had a score of 7 and 35% had a score of 8-10. There were statistically significant differences in PHI and PSA between males with and without PCa. The areas under the ROC curve for %fPSA, total PSA and PHI were 0.712, 0.746 and 0.789, respectively. PHI showed the best predictive ability to estimate biopsy results. If the cut-off criterion PHI &gt; 36.4 (77.42% sensitivity, 66.67% specificity) had been used, 41.7% of males would have avoided unnecessary biopsy. CONCLUSION The use of PHI may considerably improve the accuracy of PCa detection in patients with elevated PSA and thus reduce the number of unnecessary biopsies.OBJECTIVE The aim of the study was to analyze indicators on lung cancer (C33-C34, ICD-10) in Split-Dalmatia County in the period 2003-2012. https://www.selleckchem.com/products/sel120.html METHODS Data on lung cancer occurrence for the period 2003-2012 were obtained from the Croatian National Cancer Registry, while mortality data were obtained from electronic database of the Teaching Public Health Institute of Split-Dalmatia County. Croatian census 2011 and population estimates of the Central Bureau of Statistics of the Republic of Croatia were used to calculate the indicators. Results are presented as absolute numbers, shares (%), specific rates per 100,000 population, age-standardized rate (standard European population). RESULTS There were 2,804 registered patients with lung cancer in the period 2003-2012 in Split-Dalmatia County - 2,179 men (77.71%) and 625 women (22.29%); 2,737 people died from lung cancer in the same period - 2,117 men (77.35%) and 620 women (22.65%). Specific rates of incidence and mortality rates were four times higher among men than among women. From 2003 to 2012, the rate of incidence among men showed a significant decrease, while among women there were no significant changes of incidence and mortality. CONCLUSIONS According to the indicators of incidence and mortality of lung cancer in Split-Dalmatia County, this malignant neoplasm should occupy a high place within County public health priorities measures of prevention programme, targeting risk factors responsible for their formation.OBJECTIVE This article reviews the published studies dealing with the influence of cigarette smoking on metabolic changes and effectiveness of drugs used in the systemic chemotherapy of the lung cancer. METHODS The literature search of interactions between cigarette smoking and drugs used for lung cancer was carried out. The abstracted data mostly involved some induction of key drug-metabolizing enzymes of cytochrome CYP1A1/2, CYP2D6, CYP3A4 and isoforms of UDP-glucuronosyltransferase. RESULTS Metabolic changes are important both in the non-chemotherapy and for the drugs used in the chemotherapy. They can change pharmacokinetic and pharmacodynamic effects of drugs. Primarily, we addressed potential differences in drug effects on smokers and non-smokers. The increased clearance of erlotinib and irinotecan may have impact on effectiveness of the lung cancer therapy. The effects of taxanes and gemcitabine are more complex. CONCLUSION The evaluated studies show that continued smoking after lung cancer diagnosis is related to poor prognosis, reduced survival, risk of second primary malignancies, and increased cancer recurrence.
